I can answer a few of those questions! I'll start with the getting around part first, as you mentioned you can teleport after you've gone and attuned with a crystal in the area and that would be the fasted way to get there. The lvl 15 main story quest also rewards you with an airship pass so travel between the 3 major cities after that is pretty darn fast! After that you have your own two legs and at around lvl 25 you'll get your own personal chocobo that you can call to your side pretty much anywhere! So most of your travelling will still be done on foot or on your mount but the zones are beautiful to look at and don't take a huge amount of time to get around once you've got your chocobo.
Not a whole lot on the lore portion really and most of what I've seen get RPed is a mix of the little lore we do know about the races along with player choices that seem to be accepted. A few things I do know about the Keepers of the Moon lore is that they are a matriarchal people and tend to keep to themselves, especially the males. (Might be mixing that part up with the Seekers though so don't quote me on it.
 ) They also live in small family units instead of the large tribes that the Seekers are from.
As for the events of 1.0 I think there is a thread on here somewhere with a write up of what happened AND most if not all of the main story cut scenes from 1.0.
Hope this helps and welcome to the RPC!
